Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
If your situation is anything like that of my troop’s registered, paid, and trained adult leaders who once were also on the MBC list, you will have to complete and submit a new adult application and MB counselor application.
